Dave Stack traded a dotcom gig for the music biz when he opened
an online music marketplace, MusicStack, and tuned up the buying and selling
technology behind the music.

MusicStack is a collection of record stores, all competing on
price and selection, offering both new and used music.
"Worrying about fresh inventory is not a problem," says
Stack of his $5 million business. An uploading function updates
site selections in real time and allows the site's 3,000
sellers to manage their own wares.

"The sheer volume of items on the site makes me
different," adds the 34-year-old programmer. With 15 million
items, including CDs, vinyl, MiniDiscs and 8-tracks, Stack's
storefront eclipses retail giants Amazon.com and eBay.

The site runs itself while Stack tweaks the back-end tools from
home base--an extra space in his Cleveland home. There, Stack
watches sales soar to the tune of 1,000 items each day. Gone are
the days of building inventory by personally visiting record shops.
Says Stack, "Now sellers find me."
